To aZZ whom it may concern:

Be it known that I, GEORGE EDWIN J OHN.

sON, a citizen of the United States, residing at Los Angeles, in thecounty of Los Angeles and State of California, have invented new anduseful Improvements in Trolley-VVire Hangers, of which the following isa specification.

My invention relates to improvements in that class of trolley-wirehangers in which the guy and trolley wires are clamped by the hangerinstead of being soldered thereto.

One object of my invention is to produce a trolley-wire hanger whichwill be cheap and simple in construction, effective in operation, easyto apply, and not liable to get out of order or work loose after it isonce in position.

A further object of my invention is to provide a trolley-wire hanger inwhich the trolley-clamp and the guy-clamp will be connected with eachother by a hinge connection, so as to permit the trolley-clamp to swingin one direction or the other with relation to the guy-wire clampwithout throwing the trolleywire clamp out of line with the wire, as isthe case with those devices in which the trolleywire clamp and theguy-clamp are rigidly connected with each other. This often causes thetrolley-wire to break loose from the hanger.

My invention comprises the various features of construction andcombinations of parts hereinafter fully set forth and claimed.

The accompanying drawings illustrate my invention.

Figure 1 is a view, shown partly in vertical section, illustrating thegeneral construction of my improved hanger. Fig. 2 is a view taken atright angles to the line of View shown in Fig. 1. In this view the upperhalf of the guy clamp is removed.

One great difficulty with trolley+hangers is the tendency of the currentto leap from the trolley-clamp to the guy-wire and thus become lost andto charge the guy-wire, so that it becomes dangerous to life. This ismost liable to occur during a rain-storm, when the water saturates theinsulators and thus renders them to a greater or less extent capable ofconducting electricity. My invention is adapted in the highest degree toavoid this objection.

In the drawings, A represents a cap or inverted bell, which has a clampA secured to the top thereof, preferably formed integral therewith andadapted to clamp upon the guy or supporting Wire F. This cap thus formsa chamber a, which 1 is entirely closed at the top, and this chamber isprovided with interiorly-arranged screw-threads a.

B is a plug of insulating material arranged within the cap, and Z) areexterior screwthreads provided upon the plug and adapted to screw intothe screw-threaded cap.

0 is 'a stud which is preferably provided at its lower end with one-halfc of a hinge and has its other end rigidly fixed in the plug. The studmay be secured in the plug by any suitable means without departing fromthe spirit of my invention; but in Fig. 1 I have shown the stud securedin place by means which I consider both simple and effective. This meanscomprises pins D D, passing through the plug and through the stud. Thesepins are arranged with their ends seated far enough within the plug toavoid their contacting with the screw-threaded wall of the cap and thusdestroying the insulation. The top of the stud is also arranged belowthe top of the plug, so as to avoid contact with the top of the cap. 1

E is a trolley-wire clamp which is provided with an upwardly-projectingstem E, which at its upper end is formed into a member 0 of a hinge, sothat the lower end of the stud and the upper end of the trolley-hangerfit together and are pivoted to each other by means of a pintle orpivot-pin 0, thus forminga pivotal or hinge connection between the guyclamp and the trolley-wire clamp.

As shown in the drawings, the clamp for the trolley-wire and the clampfor the guy-wire are the same in construction, so I will describe theclamp for the trolley-wire, which will serve as a description for both.

The trolley-wire clamp E comprises a body having therethrough an openinge, within which seats the trolley-wire F. A slot c extends from thisopening upward through the body and outward to one side thereof, leavinga thin portion opposite the slit unsevered, so as to allow the twomembers thus formed to be sprung apart to allow the insertion of thetrolley-Wire into its seat. After the wire is seated in place screws Gare screwed through the clamp to bind the two members together and toclamp them firmly upon the wire. By this means a very powerful clamp isformed, and the spring-tension of the two members tends to hold thescrews from working loose.

In order to avoid any liability of the insulating plug becoming wetduring a rain-storm, I bevel the rim a' of the cap downward and outwardaway from the plug, as shown in the 3 drawings, so as to form a dripedge which will conduct any moisture away from the insulating-plu Now,having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a trolley-wire hanger, thecombination set forth of an insulator; a stud fastened within saidinsulator, one end of the stud being formed into one-half of a hinge; aclamp for clamping upon a trolley-wire, composed of one piece with itsupper portion formed into one-half of a hinge to unite with thehalfhinge of the stud; a pintle for pivoting the members of the hingetogether; and screws for drawing the clamp'tightly upon a trolley- 5wire, substantially as set forth.

2. In a trolley-wire hanger, the combination set forth of a cylindricalinsulator provided 3 with suitable threads on its outside; a studfastened within said insulator, one end of the 1 stud being formed intoone-half of a hinge; a clamp for clamping upon a trolleyuvire, composedof one piece with its upper end formed into a one-half hinge for unitingwith the 1 stud; a pintle pivoting the hinge members to each other;screws for drawing the clamp f tightly upon a trolley-wire; and ascrewthreaded socket adapted to receive the screw I threaded plug.
